I had same problem while installing windows sbs 2011 in a motherboard DH61BE which includes Ethernet Gigabit Intel® 82579V. I followed your instructions with a little difference:

1.- I used the drivers that came in the CD with the motherboard.

2.- The inf file that I modify was: /PRO1000/Winx64/NDIS62/e1c62x64.inf

3.- Here you can see lines after the modification, there are some differences in the Intel.NTamdXX.X.X because of win 7 64-bit and win server 2008 64-bit but basically the procedure is just the same that you already explained...

I've got alot of inputs to solve my problem from this tree. But the whole answer isn't here. The answers and tips is for older network adapters that I've got. So if you SBS 2011 installation still don't recognize your intel network adapter do like this.

Use the filetree and find elc62x64.inf. Open it with the texteditor.

Rightclick the unistalled network adpater in the devicelist and click the tab information.

(I only have swedish version so I don't know the english names)

Second option in that list give you the id's of your card and probably thos are missing in the file.

Third option gives you compatible id's that probably also is missing.

I took all of them and added in the file. Just to be shure that SBS2011 installation should find the driver. (I was ****** after trying 12 hours)

Navigate to PROWinx64\PRO1000\Winx64\NDIS62 and find e1c62x64.inf when you look in the file you can see that all Intel have done is alter the Server2008 section such that certain network chipsets don't get detected:

What I do above is remove everything from the [ControlFlags] section but leave the header; then you need to look at the next section down, the device you have is in the E1503 section which you can see is missing from the [Intel.NTamd64.6.1] section.

All you need to is copy the 6 lines with E1503 in from the [Intel.NTamd64.6.1.1] section; you should end up with:

recently i bought a dh77kc board, and i installed win server 208 r2 enterprise. when i was trying to install lan drivers it is showing the error : can you please help me. and i downloaded drivers from Download Center

Simon, you are a genius. Truly Intel has tried to defeat our abilities to install Server OS's on Desktop boards. I was able to use your edits to install LAN drivers for Windows Server 2008 x32, not R2, just regular Win2008, on an Intel DH77EB motherboard with a 82579V gig lan adapter. Now there is one more thing left. I have a "PCI Simple Communcations Controller" it needs a driver too. Can you recommend a .INF file edit for this one?
